IMPROVEMENT IN SANDPAPERlNG-MACHINES.

Specification forming part of Letters Patent No. 207,691, datedSeptember 3, 1878 application filed June 27, 1878.

To all whom it may concern:

Be it known that I, JOSEPH TAYLOR, of New Orleans, in the parish ofOrleans and State of Louisiana, have invented a new and usefulImprovement in Machines for Polishing Blind- Slats, &c., of which thefollowing is a specification:

Blind-slats are cut out by machinery, and the surface of them is left bythe machine in a rough state, so that they must be sandpapered andpolished to give them a good finish.

The object of my invention is to furnish a machine for sandpapering orpolishing the surface of blind-slats or other articles, whereby the workmay be done neatly and with great facility.

I employ a polishing wheel or drum rotated by competent power, andhaving its inner surface lined with sand or emery paper or any otherpolishing substances.

The articles to be polished are placed against a guide or rest next tothe polishing-surface, and'moved back and forth by hand to polish them.An exhaust-blower is connected with the polishing-wheel to draw away thedust and particles removed by the wheel from the surface underoperation.

- In the drawing, Figure 1 is a side elevation of the polishing-machine,and Fig. 2 is a vertical section through the polishing-wheel.

Similar letters of reference indicate correspondin g parts.

a a is the supporting frame or stand of the machine. bis a shaft,mounted in bearings on the frame a, and carrying the fast and loosepulleys c, for driving the machine, by a belt from the motor.

The polishing-wheel consists of a hollow cylinder, d, of wood or metal,supported loosely in rings or bearings e, which are bolted fast at f onthe top of the frame a. The cylinder (1 is revolved in the bearings e bya belt, g, from a pulley, s, on the shaft b.

h h are heads for the cylinder cl, made of metal or other material, andheld in place by staples t and screws 70, so that they may be removed atpleasure to obtain access to the interior of the cylinder (1. Theseheads serve to retain the dust made by the machine and keep it fromflying about the room.

The interior surface of the cylinder or polishing-wheel d is lined withsand-paper, emery-paper, or other polishing material, and this may beattached in sheets to the wheel (1 by gluing or otherwise, as shown atZ.

on is a rest or guide passing through the wheel d from side to side, andheld by rods 72, which are supported adj ustably inbearings 0 by athumb-screw, so that the rest 121- may be raised and lowered. 10 is anexhaust-blower fixed to the frame a, and operated by a belt from thepulley p on the shaft 1). q q are pipes from the blower 19, passingthrough the head h of the cylinder d. The head h of the cylinder d iscut away sufficiently to allow the workman to handle the work within thecylinder, and the head h has an opening opposite thereto to allow ablind-slat to pass through.

In operating the machine, a blind-slat is laid across the bottom of thewheel d, against the rest m, as shown at r, and then, by moving the slatslightly back and forth, it is polished by the polishing-surface Z. Theblower p draws away the dust from the machine while the work is beingdone. The inner circumference of the wheel at conforms to the curve ofthe slat, thereby aiding in giving the proper shape to the slat.

It is to be understood that this machine may be used for other purposesthan polishing blind-slats, as any article of wood or metal can beplaced within the machine for abrading or polishing its surface. Thefinish put upon the surface will depend upon the fineness of thematerial used upon the wheel d.

Having thus described my invention, I claim as new and desire to secureby Letters Patcut- 1. The combination of a rotary drum havingpolishing-surface on inside, a movable rest, and an exhaust blower, asshown and described, for the purpose specified.

2. The blower 10, in combination with the polishing-drum d and heads hh, substantially as and for the purposes set forth.

JOSEPH TAYLOR.
